From f313579fbb5a5318367521793dc24d2567da2fde Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Tue, 10 Jan 2017 12:53:07 +0000 Subject: Introduce flags NODE_NOSRC and NODE_NOPRT for AST nodes. Use them to mark generated nodes and nodes that shall not produce output. Let -Ttree output mode display these new flags. Use NODE_NOSRC for .Ar, .Mt, and .Pa default arguments. Use NODE_NOPRT for .Dd, .Dt, and .Os. These will help to make handling of text production macros more rigorous. --- roff.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'roff.h') diff --git a/roff.h b/roff.h index 19ec50f4..783e5daa 100644 --- a/roff.h +++ b/roff.h @@ -1,7 +1,7 @@ -/* $OpenBSD$ */ +/* $Id: roff.h,v 1.38 2017/01/10 12:53:08 schwarze Exp $ */ /* * Copyright (c) 2008, 2009, 2010, 2011 Kristaps Dzonsons - * Copyright (c) 2013, 2014, 2015 Ingo Schwarze + * Copyright (c) 2013, 2014, 2015, 2017 Ingo Schwarze * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above @@ -109,6 +109,8 @@ struct roff_node { #define MAN_VALID MDOC_VALID #define MAN_EOS MDOC_EOS #define MAN_LINE MDOC_LINE +#define NODE_NOSRC (1 << 8) /* Generated node, not in input file. */ +#define NODE_NOPRT (1 << 9) /* Shall not print anything. */ int prev_font; /* Before entering this node. */ int aux; /* Decoded node data, type-dependent. */ enum roff_type type; /* AST node type. */ -- cgit v1.2.3
